Overview
The DG412EUE+T is a quad, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally open configuration with four independent channels in a 16-pin TSSOP surface-mount package. Key electrical specifications include a maximum on-resistance of 85 ohms and a supply voltage range from 9V to 36V for single supplies, or ±4.5V to ±20V for dual supplies. The device operates within a temperature range of -40°C to +85°C, drawing a maximum supply current of 600 µA. It supports a DC switch current of 30 mA and offers switching times of 250 ns (on) and 125 ns (off).
Feature Summary
- Quad SPST configuration providing four independent signal paths.
- Normally open logic state for standard switching applications.
- High voltage tolerance supporting wide single and dual supply ranges.
- Low power consumption suitable for battery-operated systems.
Applications
- Signal routing in data acquisition systems.
- Multiplexing sensor inputs in industrial control panels.
- Audio signal switching in professional equipment.
- Test and measurement instrument front ends.
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation, as legacy variants may differ. Ensure the supplier provides valid traceability for the Analog Devices/Maxim Integrated brand. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.
Selection Notes
Select this component when a quad SPST switch with high voltage capability is required. Compare on-resistance values against other models if signal integrity at low voltages is critical. Consider the TSSOP-16 footprint constraints during PCB layout. Verify that the 30 mA DC switch current meets the load requirements of the target application circuit.
Part Context
This part belongs to the DG412 family of improved CMOS analog switches. It shares architectural similarities with the DG411 and DG413 but differs in logic state configuration. The EUE+ designation specifies the lead-free, TSSOP-16 package variant. It serves as a robust solution for general-purpose analog signal switching in mixed-signal environments.
Replacement Considerations
Direct functional substitutes include the DG411EUE+ (normally closed) and DG413EUE+ (mixed NC/NO). For pin-compatible alternatives, verify the on-resistance and supply voltage limits match the original design requirements. Cross-reference package dimensions to ensure mechanical fit without redesigning the PCB footprint.
